problem with proxy

Hi experts

I can not "Change/Regenerated" a proxy that existed before migration of XI 3.0 to PI 7.0 and SAP BW 6.40 to 7.0, and I execute the transaction SPROXY and I saw that is not a Software Component version of BW (SCV BW 3.5) so I can not "Change/Regenerated" a proxy because it is the SCV

can someone tell me how I can resolve this problem? please

I thank you much
